Very low densities… Read more »
Since early 2020, growers and agronomists have been nervous about the prospect of fall armyworm (FAW; Spodoptera frugiperda) invading their crops. So far, the majority of significant and damaging FAW infestations have been recorded from sweet corn, maize, and sorghum crops, with some isolated outbreaks in horticultural crops such as ginger and capsicum. Occurrences in other crops have been a… Read more »
Fall armyworm (FAW) are still active across the Northern Grains Region, but inland Central and Southern Queensland have not experienced continuous population build up in crops since the first immigration of moths in September–October. One of the major contributors to this continuing low pressure is probably the very high natural enemy (beneficial) impact on FAW. A number of very common… Read more »
With the detection of fall armyworm (FAW, Spodoptera frugiperda) throughout Queensland and now in major cropping regions in NSW, growers are wondering about the best management options for protecting their summer cereal crops. The latest research from NSW DPI provides information that can assist growers in deciding the most appropriate course of action for managing outbreaks of fall armyworm if… Read more »
